Isotrias rectifasciana

(Haworth, 1811)

---

Wingspan 11-16 mm.

This species is sexually dimorphic, with the males being generally larger and with less distinct forewing markings.

Despite being reasonably frequent in parts of England, and occurring in Wales and Scotland, the life history of the early stages is imperfectly known, though in captivity they have fed on hawthorn (Crataegus).

The adult moths fly in May and June, from dusk onwards.
